3.2.1. Command Mode
8
• The Argonaut can send and receive commands related to all aspects of instrument
operation.
• You can enter the command mode from any other mode by sending a BREAK (§3.4).
• You can enter the command mode from the data acquisition mode using the run-time
command “+++” (§3.15).
• You can put the Argonaut into any other mode only from the command mode.
• To enter the data acquisition mode from the command mode, use the command Start.
• To enter the deployment mode from the command mode, use the command Deploy.
• To enter the SDI-12 interface mode from the command mode, use the command sdi12.
• To enter the sleep mode from the command mode, use the command PowerOff.
• If the Argonaut is left idle in the command mode for more than five minutes, it will enter
the sleep mode to conserve power.
3.2.2. Data Acquisition Mode
• Data acquisition mode is used for real-time data collection for which you are typically
connected to an external power supply and computer or data logger.
• Data acquisition mode is entered from command mode with the command Start. After
the Start command, the Argonaut takes a few seconds to initialize and then begins data
collection.
• In data acquisition mode, the Argonaut ignores the deployment parameters StartDate and
StartTime.
• If the internal recorder has been enabled (Recorder ON), data are output both over the
serial port and to the internal recorder. If the recorder has been disabled (Recorder OFF),
data are sent only to the serial port.
• You can exit the data acquisition mode and return to the command mode by sending a
BREAK (§3.4) or by using the run-time command “+++”.
• While in data acquisition mode, the Argonaut can enter a low-power state between pings
and between samples. This state is similar to, although not the same as, the sleep mode.
The Argonaut will enter the low-power state if the system command AutoSleep is set to
ON (the default setting). See §3.7 regarding the AutoSleep command and §3.15 regarding
the effects of the power saving state on the run-time commands.
3.2.3. Deployment Mode
• Deployment mode is used for autonomous data collection (internal recording, typically
with battery power).
• Deployment mode is entered from command mode using the command Deploy.
• In deployment mode, the instrument starts data collection at the date and time specified by
StartDate and StartTime. If the current date and time are after the specified start date
and time, the system begins data collection immediately.
• In deployment mode, data are always stored to the internal recorder regardless of the
Recorder ON/OFF parameter.
• In deployment mode, the Argonaut will always enter the low-power state between pings
and between samples regardless of the AutoSleep parameter (AutoSleep is forced ON).
• Because of the power saving state, the run-time commands (§3.15) cannot be used.
• You can exit the deployment mode and enter the command mode by sending a BREAK.
